With a lash of pink lipstick, the mother-of-four highlighted her natural beauty as she set out for her day.

Her outing came just a few days after she stepped out bare-faced in New York.

And while her eyes looked in need of rest, the rare appearance proved that even without a myriad of products upon her face, she is still a natural beauty who easily looks a decade younger than her 39 years.

But despite the lack of synthetic foundation or lipstick slapped on her face, the Project Runway host still screamed 'supermodel' with her wardrobe choice.

Out in the rain: Heidi made her chic look appear effortless – even in the dreary New York City weather

Heidi opted for an all-black ensemble, but the clothes were far from dull.

The daring skirt had a generous slash up the left leg, exposing her thigh as she walked along.

Her T-shirt fabric was cut-out all along the shoulder and chest area in a punk crochet style, providing a cheeky expos to onlookers of her bra.

The day before, she managed to even make overalls look good, on an outing in New York with her four children.

The model announced her separation from husband Seal in January, four months before their seventh wedding anniversary.
